General-purpose curing accelerator, used to accelerate curing under the following conditions: the temperature is lower than 10°C, the metal surface activity is low, the filling gap is large, or the curing needs to be accelerated. Activate the inert, non-metallic surface to enhance the filling of the gap, increase the curing degree, and promote the low-temperature curing. Suitable for 5200 series, 5500 series, 5600 series anaerobic adhesives.
